I have a class Trans, with properties siteID and TID. I have a generic list of this class, TransList = list(Of Trans).
Now I want to find the Trans in TransList where the siteID is 3 and the TID is T1. There will only be one record. I want to then update this Trans in the TransList (so I need a reference to the Trans). I am trying to do the following, but it doesnt like it.

I'm trying to create a control out of a class I found, and one of the overridden functions is the following:
protected override void PerformDataBinding(IEnumerable data)
However, when I try to build the control I'm getting the error as shown in the subject. I've tried searching, and it seems the signature for the original function matches the one I have, and all other solutions I've seen uses the same signature.
I've had a bit of a problem trying to bind a generic list to a repeater. The type used in the generic list is actually a struct.
I've built a basic example below:
[code]....
I then create two fruits using the struct (apple and orange). These fruits are then added to the list.
Finally, I bind the generic list to the DataSource property of the repeater...
The markup looks like this:
[code]....
I expect to see the fruit name and price printed on the screen, separated by a horizontal rule.
At the moment I am getting an error relating to actual binding...
**Exception Details: System.Web.HttpException: DataBinding: '_Default+Fruit' does not contain a property with the name 'FruitName'.**
I am trying hard to update a business object inside a List<>.
I am using a checkbox list
When a checkbox list item is clicked I check if it exists, if yes I mark it as Dirty (means the user unchecks an item)If not, I add a new item to the list (means the user clicks a new item)and store it in view state
How do I update the Generic List with the Dirty Object ?
On form update, do I foreach and make separate lists of dirty and new objects to send to DB layer or would you recommend any other way ?
Here is my code.
protected void cblExclusions_SelectedIndexChanged(object sender, EventArgs e)
{
if (cblExclusions.SelectedIndex != -1)
{
ftExclusions myExclusion=new ftExclusions(); // Business object

sort List-generic object by two parameters
View 1 Repliesi'm having a gridview with textboxes and i'm allowing user to enter all the textboxes and when submit button is clicked, I'm constructing the Object and adding all the rows to LIST class.,After that i'm putting that LIST elements in a session. Everything is fine, But when i try to cast the session object to LIST type and pass it to XML serialization, I cannot see the elements in the list and it is showing LIST as NULL. I can see the generated XML string with ROOT and my classname as attributes without no data.

I have a list of Controls that are held in a List<Control> and I want to be able to check their type. As my list holds only Controls, doing typeof() isn't going to get me too far, I want to be able to ask if List<Control>[0] is a Checkbox, TextBox, Label, etc.How do I go about finding out what specific type of Control I have in my list?
View 7 RepliesI'm trying to create a validation layer that will contain methods to validate all my objects (in my Business Objects layer) .. but when I try to reference both the validation and business objects to each other I get a circular dependency error .. so I've decided to create a new layer (BLL) to validate the objects for me and I'll be able to reference both the validation and the object layers.
so I want to build some kind of class/interface -I don't know what fits more- to be like a generic type or a parent type that my method could accept it as a parameter and check for it's Name/ID property. Instead of defining a new method overload for each object type I have

I need the 1 since it's a foreign key in another table. For the life of me, I can't get this to work like this.

View 2 RepliesI have a method like:
public T Get<T>(string key)

Now say I want to return "hello" if the type is a string, and 110011 if it is type int.
how can I do that?
typeof(T) doesn't seem to work.
I ideally want to do a switch statement, and return something based on the Type of the generic (string/int/long/etc).

For an MVC 2 app that relies on many partial views and almost exclusively uses Ajax for POSTs/GETs, what would be the best way to implement the setting, passing, retrieval and display (using a JavaScript modal) of these messages?
My forms all POST (by way of jQuery $.ajax) to actions that return partial views (html) that are used to update a in the "success:" part of the $.ajax function.
I was hoping for some sort of mechanism in the master view that could "listen" for any messages that any of these partial views might be "delivering"--through their ViewData, for instance.

In Asp.net Web forms why must a user control be partial? I tried to remove the partial keyword and it says: Missing partial modifier on declaration of type 'test'; another partial declaration of this type exists
Where is the other declaration?I am trying to pass a generic type with the user control how can I do that? I can't unless I change the other declaration too. I couldn't find it so I removed the partial keyword.Note:
you do have 3 files if your making WebApplication but if your making website you only get 2 files?
UserControl.ascx
UserControl.ascx.cs
so in website where is the other declaration?the reason i want generic is because im making a Grid User Control so i want to pass the type the datasource is going to have.
I have built a dataset named Transaction_Time.I called it on Page_Load
Transaction_Time tranTme = new Transaction_Time();
put it in the session.
Session["Transaction"] = tranTme;
Then I call that session and cast to dataset.
DataSet dstTranTime = (DataSet)Session["Transaction"];
I got the following error.Unable to cast object of type 'Transaction_Time' to type 'System.Data.DataSet'.
[InvalidCastException: Unable to cast object of type 'Transaction_Time' to type 'System.Data.DataSet'.]

It is OK for some other pages. But for some page, it doesn't.

I have an asp.net web site where I'm trying to resolve what looks like a problem with ASP.NET AJAX:
Microsoft JScript runtime error:
Sys.ArgumentTypeException: Object of
type
'Sys.Extended.UI.AccordionBehavior'
cannot be converted to type
'Sys.UI.Behavior'. Parameter name:
instance
I've googled around a lot, and looked at the code presented (see below, no idea what it means) but no luck.
I've tried changing scriptmanger scriptmode to release, and a bunch of other things too.
Details:
Visual Studio 2010
ASP.NET 4.0
Ajax control toolkit 4.0
jQuery 1.4.2
jQuery UI 1.8.5
JS Code the error occurs in, inside ScriptResource.axd:
dispose:function()
{
var c=this;
b.UI.Behavior.callBaseMethod(c,eb); --------- this line
var d=c._element;
if(d)
{
var f=c.get_name();
if(f)
d[f]=a;
var e=d._behaviors;
Array.remove(e,c);
if(!e.length)
d._behaviors=a;
delete c._element
}
}

*Update: *
Added accordion control declaration as requested, is there anything else I can add that could be useful?
Does anyone have any idea about this error at all - am I right in thinking it's MS AJAX not playing nicely with other javascript (probably jQuery UI) on the page?
I'm building a website in vs2010, i generate usercontrols (aspx and ascx pages), if i run the website i get the error : unable to cast object of type 'ASP.ProjectName_master' to type 'ProjectName.master'

I have a main page with several menu choices, one of which launches an ajax enabled window. The following pattern occurs:If I:
1) Launch site
2) Select menu choice listed on master page that is not ajax enabled
3) Select menu choice that launches ajax enabled popup.
4) close pages
All is OK.If I repeat the steps, but in step 2 I select an ajax enabled page and them launch popup, I get the following error:Message: Sys.ArgumentTypeException: Object of type 'Sys.UI._Timer' cannot be converted to type 'Sys.UI._Timer'.I have spent days on this and have been unable to solve it. If I remove the ajax ToolkitScriptManager and update panels from any of the pages and launch the popup, it works. Can anyone offer some guidance?that are not ajax enabled and then selethat includes an ajax enabled popup window. T
I'm busy writing a handler to serve various documents for download or presentation in web forms pages. The documents range from various image formats, to PDF, to MS Office documents, to generic binaries. My basic draft of the download process is as below:
[code]....
However, I have some misgivings about lumping all documents together as application/octet-stream, and I would prefer, if feasible, to use a more specific content type per document type. I have a DB table for document types where I could store this. Am I going in the right direction, and if so, where can I find a suitable starting list of content types for document types?
I'm writing a formbuilder for our CMS which dynamically loads bespoke controls into panels within a repeater.
The bespoke controls all inherit from, lets say 5arx.FormBuilder.FormControl, a base class which defines abstract methods for initialising, validating, repopulating, gathering submitted data from them. Controls range from simple text fields to complex, composite client-side controls.
It all works very well, but I've noticed something I feel is anomalous. During the course of writing code to retrieve form controls. gather their data and persist it to my database I noticed that their type reverts to the way objects get typed if you write your code in the (v. irritating) VS 'website project' mode.
So, for example a control that is defined as living in a namespace and being of type
5arx.FormBuilder.FormControl.MyBespokeControl
Sarx.FormBuilder.FormControl.MyBespokeControl
at runtime reports its type (via simple call to GetType()) as being of type:
ASP.5arx_FormBuilder_FormControl_MyBespokeControl
ASP.Sarx_FormBuilder_FormControl_MyBespokeControl
Getting the BaseType property will correctly retrieve the underlying class, but it is perplexing to me why this should be happening. Particularly as I spent much of the summer refactoring our app from its original form as VS Website project (complete with shared code in the App_Code folder and other nastiness) to the (IHMO) correct web application project + supporting claass libraries so that we would have control over our namespaces and not get everything compiled into the ASP.x namespace
EDIT: Modified the (hypothetical) example root namespace.
I got this error and do not know how to solve it.
